The decal is bugging through the pet.
I have tried placing the decal further away from the pet to se if its clipping because its too close but it was still bugging.
When im opening 3 eggs, and the pet positions on the sides, it doesnt bug, only when the pet is in the middle. Also other decals doesnt create this problem.
It definitely looks like it is overlapping with the body.
I take it that the decal is not directly parented to the body, and is instead parented to another part?
If so, is it possible for you to parent it directly to the body (if only for the opening sequence)?
Thank you i tried that approach before and it worked 
btw, idk if this is an approriate place to ask but i see you’re studing software engineering and im deciding which degree i want to pursue after the summer. As you’re a roblox developer, did your choice depend a little that you like game development and if so why didn’t you prefer to take for example data science which has more maths and can be useful when making games.
My uni didn’t offer a game development degree, so I just picked the closest one! (it already contains a bit of maths, so I will still learn what I need).
